Syook is an established startup headquartered in Bengaluru, working in the B2B space. We are currently on the path of high growth and productivity, and great culture building (because we know the two go hand in hand)! We are looking for folks who will ask questions like why/why not, what can I do to make this better, how can I help the company and most importantly, what can the company do to help you.

Our flagship product Syook InSite allows businesses to visualize their operations, providing information that can easily translate into measurable impact on the bottom-line. InSite is an Industrial Internet-of-Things (IIoT) solution that uses Bluetooth Low Energy (BLE) beacons to generate highly-accurate location data of all your resources (both assets and people), at much lower costs than https://syook.com/rfid-vs-ble-vs-uwb-vs-wi-fi/">comparable technologies. The result: Quick RoI and Improved Operational Performance. It’s Industry 4.0, ready for deployment!

First and foremost, we're looking for people who are excited about what we're doing -- you don't need to know anything about IoT, but should be excited to learn. We're building in an entirely new space, so you'll be able to use creativity to help us solve problems and delight our customers.

Our product stack is MERN (React, Node + Express, MongoDB) with a few services also written in Java and Go and we use React Native on mobile.

We’re looking for someone who has always loved to be on the creative side of things and enjoys creating user experiences that are inviting, intuitive and impactful. You must enjoy designing the layouts of the product, the navigation and the complete look and feel of it. 

A day in your role will involve any of the following (or a combination):

• Develop new user-facing features
• Build reusable UI components and libraries for future use (for web and mobile)
• Ensure the technical feasibility of UI/UX designs
• Optimize application frontend (web and mobile) for speed and scalability
• Ship out bug free code using TDD
• Work towards more stability & scalability of the frontend
• Understand the requirements and give adequate time estimates for the features
• Coordinate with QA for every feature and make sure releases are bug free

This list is not exhaustive at all, and you'll have a lot of autonomy over your work.

This is a full time position based out of Bengaluru with the option of working remotely few days of the week. During the interview, you'll be able to share what you're most interested in.

1. We're working to solve a massive global problem and help organizations be more competitive. We love solving problems using technology and are bridging a massive gap in the operations excellence domain.
2. We're small, so you'll be able to contribute efficiently and without bureaucracy. You'll quickly have responsibility over big areas of our product.
3. Our team has a wide range of experiences (Oilfield, Telecom, Psychology PhD, etc.) and are excited to learn from you, too.
4. You'll be able to work independently and set your own schedule. We don't micromanage and will help you do great work. We trust our people and believe that each person here puts their best foot forward.
5. We'll mould your role to shape a career you're excited about. We care a ton about your satisfaction and job happiness, and will help prep you for whatever you're looking for in the future.
6. We work hard and also highly value balanced work/life. We care about family and your own personal development, and don't expect for you to be always engaged with work.

1. We're small (35+ people in the company now), so if you like more established companies, it's not (yet) the right time. You'll help build our company's culture.
2. Since we're an early stage startup, projects and priorities may shift.
3. Our customers love us, and there's a lot we can improve. It's a great place to be, but it means there's some jank. (Nothing too scary! 😃)
4. We can't (yet) provide constant close mentorship for junior developers. As we grow, we'll get a lot better at this.
5. Since you'll have a lot of responsibility and creativity over projects, they may not be defined perfectly initially. You'll be expected to bring your own experience and perspective to help us do the right things, and raise flags if you think we should do things differently.

None of these are requirements, but do describe the kinds of people that we think would be most effective at Syook right now.

1. Love thinking broadly about problems and thinking creatively about how to solve them efficiently.
2. Happy to try things out to validate new features, and move on if they no longer solve a problem.
3. Excited for a front-row seat into a fast growing, early stage company. Things will change a lot!
4. Enjoy thinking through trade-offs, with both mindfulness of short-term needs and our long-term direction.
5. Happy writing documentation so that others can ramp up super easily and you're never a single-source-of-failure. We're a bit too small to have silos.
6. You are driven and care about doing a good job and improving your craft.
7. You have a growth mindset, can keep up with the latest technology changes and trends and suggest enhancements based on these 
8. Most importantly, you’re the kind of person who is friendly, approachable, ready to help others and personally driven to put your best foot forward.

Technically these are some of the things we would like for you to have to be able to contribute effectively in this kind of a position:

1. You are fluent working with client-side scripting and JavaScript frameworks, in particular React and React Native along with state management libraries like Redux. 
2. You are proficient in understanding of web markup, including HTML5, CSS3
3. You have knowledge of developing mobile apps 
4. You can write non-trivial programs in Javascript
5. You can write clean, modular code in either Object-Oriented style or Functional style
6. You are comfortable with Test Driven Development
7. You are fluent in using the tools of the trade: Testing, Editors, Git, Command line, Slack

Apart from the above it would be a plus if you also have

• Knowledge of Docker
• Open source contributions 

Since we're an early-stage startup, we constantly have to ask "what gets the most value, cheaply, to validate our assumptions?" We build some things to last a long time, and others as prototypes.

We use linting, e2e testing, CI CD, observability logging, and production probers. We've documented both our web and mobile apps so that you should be able to get started easily—and if you need help, we'll absolutely improve our docs—and contribute your first day.

We recognize the value of maintainability and keeping our developer experience nimble. Our sprints are for 2 weeks and we push releases to production as per this schedule.

You'll help push us to be our best, and we're excited for recommendations and insights you have as you join. You'll be an owner and contribute towards how we work.

We want you at your best, and won't be giving you gotcha-style algorithms questions. We want to get to know you, hear about what you're interested in, and learn about what you hope to do in the future.

You'll first talk to Sarlaksha or someone from the People Services team (over phone or video) and won't need to prepare anything in advance. The goal of this conversation is to get to know you and mutually explore if we might be a good fit for each other. You'll learn more about Syook and have a chance to ask any questions about our company, team culture, and product.

The conversation will also revolve around your technical experience. We'll talk about frameworks you've used, how you make technical decisions, types of problems you like to solve, etc. You won't need to prepare anything in advance.

This is primarily used to get a better feel for your experience, how you work, and where you may fit in. It'll be used to design the rest of the interview process.

Through this and the next steps, you'll meet more people in the company so we can get to know each other.

Everyone has different strengths, and we want you to do your best. Our goal is for you to clearly demonstrate your technical aptitude. We're open to accommodating what would work best for you.

We can choose mutually between several different options:

1. A live pair coding session where we'll work through some problems.
2. Working through similar problems independently as a take home challenge.
3. Presenting any previous work you've done (example: open source, side project, or even another interview you did).

We will talk to a few people you've worked with before to learn more about how we can best work with you. We expect to hear great things, so this is primarily so we can work with you as effectively as possible.
